At the fire scene, in addition to waiting for the firefighters to rescue, more importantly, we have the correct escape knowledge and seize the best escape time. If there is a fire downstairs, do you run upstairs as soon as possible? Is it safest to have water in the bathroom? Should I take off my flammable clothing immediately when I am in a fire? ......The reporter sorted out the "six questions and six answers" of hot fire issues, and learned fire knowledge with you, so that you can not panic when you encounter a fire.
Q1: If there is a fire in a high-rise building, if there is a fire downstairs, should I run upstairs as soon as possible?
Trapped in the fire scene, smoke is one of the deadliest existences, once encountering this situation, you should immediately determine the fire area, and escape in the direction away from the smoke. The safety passage of some buildings is designed with negative pressure, and if you confirm that there is no smoke in the safety passage, you can quickly escape downstairs. But in any case, remember not to take the elevator, due to the special design of the elevator shaft, it is easy to cause the chimney effect, the smoke first permeates into the elevator shaft, and the elevator is a relatively closed space, and it is very easy to cause serious damage to the respiratory tract when people are trapped in it.
Here's how:1. If there is smoke in the hallway, and the smoke is very thick. If the doorknob is hot and smoke seeps through the crack in the door, it is recommended to block the crack in the door with a soaked towel or clothing to reduce the smoke ingress, and at the same time call the police at 119** to inform yourself of the location of the trapped room and wait for help. In the meantime, it is necessary to constantly wet the entrance door with water to prevent the outside from being baked at high temperatures and the spread of the fire, so as to buy more time for yourself and wait for rescue to come! 2. If the door is opened, there is no smoke or the smoke is small. The door may be opened in three situations:1The fire in the hallway may not be big; 2.** Lit: In the downstairs resident's house, there is not much smoke coming out for the time being; 3.The fire door in the stairwell is closed, and the smoke does not come up. 3. If you want to choose to escape to the rooftop, the three conditions that must be met are:1.Your home is very close to the roof; 2.There is an exit from the roof and it is not locked, and the stairwell is not blocked by debris; 3.If there is smoke in the stairwell, you need to get to safety in one breath, but there are certain risks associated with this practice.
Q2: In case of fire, it is safest to hide in the toilet or bathroom with water?
Many people mistakenly believe that "the safest place is where there is water", so they take refuge in the bathroom in the event of a fire, but in general, the bathroom door must leave a ventilation gap in order to exhaust the air, so it is impossible to block the smoke. In the event of a fire, the glass is very easy to be shattered by high temperatures, so a large amount of smoke can quickly escape in. At this time, even if there is water, it is not very effective in blocking the entry of toxic fumes from outside. In addition, most of the door panels of the bathroom are wooden doors or plastic doors, and there is no fire prevention function, as soon as it comes into contact with the fire source, it will be burned, and if the bathroom is not set up with an external window, the air can not circulate, and it is impossible to call for help, "hiding in the bathroom is equivalent to death". If you are trapped indoors by the smoke of a fire, you can choose an open space such as a balcony or a bathroom with a window according to the actual situation. If you find that the exit is blocked by the smoke of the fire and you have no protective equipment, do not rush out rashly, you should return to the house, block the crack of the door with wet towels and clothes, and pour water on the door to cool down. Therefore, in the event of a fire, do not think about running in the same way, but choose a scientific way to avoid danger according to the actual situation of the fire.
Q3: Is it outdated to cover your mouth and nose with a wet towel in case of fire?
In a variety of fire escape methods, covering the mouth and nose with a wet towel is still a possible way to protect yourself, especially in the early stage of the fire, covering the mouth and nose with a wet towel can effectively block the smoke, reduce the inhalation rate of respiratory smoke and dust, and avoid respiratory burns, but if the fire is too fierce, then neither the wet towel nor the smoke mask will have much effect, do not try to cross the smoke area at this time, the most important thing is to find an area away from the smoke and wait for rescue.
In the event of a fire, you can protect yourself by folding a wet towel in half 3 times to cover your mouth and nose. Although the more layers of wet towels are folded, the higher the smoke insulation rate, such as 60% after folding 8 layers, and 90% after folding 16 layers, but the more folded layers, the greater the obstruction to breathing, so it is not that the more folded layers, the better, and it is generally recommended to fold it in half 3 times. Families with the conditions can also be equipped with some smoke masks in case of emergency.
Q4: In the event of a fire, you should wave bright clothes and tell the fire and rescue personnel where you are trapped. Is this method correct?
That's right! But before that, there is a very crucial step to buy precious time for your rescue. The door to the house must be closed. The reason for the closure is that it is outside**, and you can't get out of the bedroom in the first place, so you retreat to the balcony to wait for rescue. But if the door is open, and the whole window is open when you beckon to help, then the smoke will quickly reach where you are, so you are in a very dangerous environment. In this fire situation, it is important to remember that the door must be closed to block the entry of toxic fumes.
Q5: Should I take off my flammable clothes immediately if I am wearing flammable clothes in the fire?
That's right. For example, the ** that women often wear is easy to ignite, and the fire will spread quickly, and it will be tightly connected to the epidermis after being burned, and the damage will be greater. Not only **, but other flammable clothing should also be removed as soon as possible. The correct way is to escape from the fire and take off flammable clothes as soon as possible! Female friends should pay attention: go to barbecue, hot pot and other places with fire sources, and try not to wear **.
Q6: Will the fire be like in the movie, open the door?
This is something to be aware of. When escaping from a fire, you may have to open door after door. Before opening the door, be sure to touch the door to see if it is hot. If the door is already hot, and even black smoke is coming out of the cracks, don't open it! At this point, it is clear that going out of here is no longer the best choice. The correct approach is that the four walls of the general building are firewalls, which can be isolated from fire for more than 3 hours. During this time, you can plug the crack of the door with a damp towel to prevent toxic fumes from entering the room, and water the door more often to prolong the time it will burn through. At the same time, pull a piece of brightly colored fabric or a beautiful dress, and shake it at the window to attract the attention of others. **From Xinhua**).
